Arizona Diamondbacks farm system preliminary grade breakdown

I am working on the Arizona Diamondbacks prospect list. I am no longer foolish enough to give an exact ETA, but it is going more quickly than the Astros list at least. Here is an early look at the grade breakdown. This is likely to change some in the end but it gives a general idea of what I am looking at.

Arizona Diamondbacks  33 players graded

One Grade A
Two Grade B
Seven Grade B-
10 Grade C+
13 Grade C

Have fun speculating!
